Often asked: A Bacterial Cell With Which Of The Following Modifications Might Be Resistant To Antibiotic Quizlet?


Which of the following is true regarding the resistance of bacteria to antibiotics quizlet?

Which of the following statements is TRUE regarding antibiotic resistance in bacteria? All bacteria are naturally resistant to all antibiotics. Some individuals in bacterial populations naturally have the mutations that lead to resistance. Exposure to antibiotic caused the mutations that lead to resistance.

Which of the following contributes to the development of antibiotic resistance in bacteria?

Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

Which of the following processes in bacteria can be interrupted by antibiotics quizlet?

Antibiotics can interrupt cell wall and membrane formation, ribosome function, and DNA replication, transcription and translation within bacteria.

Is an example of a bacterium that is highly resistant to antibiotics quizlet?

MRSA), which are strains of the bacterium that are resistant to the action of methicillin, and related beta-lactam antibiotics (e.g. penicillin and cephalosporin). MRSA have evolved resistance not only to beta-lactam antibiotics, but to several classes of antibiotics.

What has led to the evolution of antibiotic resistant bacteria quizlet?

evolution of antibiotic – resistant bacteria? The presence of an antibiotic in an environment leads to the selection of those individuals that are most resistant to it. some insects have a gene that makes them resistant to the pesticide. the frequency of resistant insects in the population increases.

Which are true of antibiotic resistance?

Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic – resistant germs are difficult, and sometimes impossible, to treat.

What are some examples of antibiotic resistant bacteria?

Examples of bacteria that are resistant to antibiotics include methicillin- resistant Staphylococcus aureus (MRSA), penicillin- resistant Enterococcus, and multidrug- resistant Mycobacterium tuberculosis (MDR-TB), which is resistant to two tuberculosis drugs, isoniazid and rifampicin.

What are the causes of antimicrobial resistance?

The main cause of antibiotic resistance is antibiotic use. When we use antibiotics, some bacteria die but resistant bacteria can survive and even multiply. The overuse of antibiotics makes resistant bacteria more common. The more we use antibiotics, the more chances bacteria have to become resistant to them.

What is the best antibiotic for a bacterial infection?

Bacterial infections are treated with antibiotics such as amoxicillin, erythromycin and ciprofloxacin. There are many different types of antibiotic, with different ways of working; the choice depends on the type of infection you have. Fungi commonly cause skin infections such as athlete’s foot and ringworm.

Which is more fit antibiotic resistant bacteria or antibiotic sensitive bacteria quizlet?

Antibiotic – resistant bacteria are more fit for an environment where antibiotics are used frequently. The ability to resist antibiotics may cause bacteria to be less fit in other environments where antibiotics are not present. Bacteria that are sensitive to antibiotics have a reproductive advantage in all environments.

What role does antibiotic resistance play in disease quizlet?

Antibiotics kill bacteria causing the illness, as well as good bacteria protecting the body from infection. Some bacteria give their drug- resistance to other bacteria, causing more problems.

Why is the increasing bacterial resistance to antibiotics a bad thing quizlet?

Why are antibiotic resistant strains a problem for people infected? Because they aren’t immune to the new strain and so there is no effective treatment and the infection spreads between people.

What is antibiotic resistance and how does it occur quizlet?

Terms in this set (11) What is Antibiotic Resistance? -Ability of bacteria or other microbes to resist the effects of an antibiotic. -Natural selection gives resistant organisms an adaptive advantage.

How do bacteria that are sensitive to antibiotics become resistant quizlet?

Exposure to antibiotics therefore provides selective pressure, which makes the surviving bacteria more likely to be resistant.

How does antibiotic resistance arise How do hospitals and feedlots contribute to this phenomenon?

Answer Expert Verified Antibiotic resistance arises due to the evolution of the organisms they are designed to destroy. Hospitals ‘ overuse of antibiotics quickens the process, as does the administration of antibiotics to feedlot cattle, whose meat is consumed by people.
